ROLLER-BEARING.

To (ti/Z whom it may concern:

Be it known that 1, ARTHUR JACOB MORSE,

, a citizen of the United States,-residing at Torrington, county of Litchfield, State of Con- 5 nectic'ut, have invented certain new and use-- ful Improvements in Roller-Bearinga-of which the following is a specification.

My invention relates to roller-bearings,

and as herein embodied is designed for use in mounting vehicle or other wheels, rotating elements,- &c.

The object of the invention is primarily to producea roller-bearing possessing advan-.

tages in point of tractive efliciency-that is 15 to say, a balanced bearing self-acting in takfurther object is to ma ntain absolute parallelism throughout the roller systemthat is to say, an automatic adjustment or.

' compensating action for wear u on the" surfaces of the cooperating parts, an thus insure videin the event of the rollers of the bearing becoming obstructed or lockedifor the free and continued rotation of the .wheel or other element mounted thereon. For convenience .of illustration I have lim- -ited the showing in-the accompanying drawigSST/O the application of the invention as an bearing; but it will be understood that its use is not in any wise restricted, as it Z-niay obviously be employed for other purpose's, if desired. r .-1 In' the drawings, Figure 1 is a central sectional viewtaken lengthwise of the axle.

o Fig. 2 is a detail view of one of the bearings removed. Fig. 3 is a similar view of the:sec-

-.tional rackor case in which the rollers are j ,,mounted, and Fig. 4 is a detail view showing 1 a portion of the rack from which the rollers 4' 5 have been removed. I e

Rferringnow to the drawings, 1 represents a portion of an axle, and 2 the sectional metallic hub of a wheel mounted thereon.

The hub of the usual hollow form is counterso bored, as indicated at 3, to receive two sets Specification of Letters Patent. Application filed January 24,1906. Serial No. 297,572.

Patented April 9, 1907.

7 8 9 10, which are combined in pairs by be-' ing arranged one within theot-her and as assembled form a race for a series of doublecone rollers 11, carried in a rack 'or case 12. The cooperating pairs of rings of eachset of bushings. are relatively spaced, as indicated at 13, to clearthe central portion of-thet' rollers and permit limited endwise movement or play thereof, such as would occur when, by reason of uneven wear, the rollers tend to turn faster at one end than the other. The rollers are thus rendered self-adjusting -to compensate for wear and maintain themselves in parallel relation throughout the entire series.

The inner rings 7 and 8 of the bushings are fitted to turn freely upon the bearing por tions 6 of the axle between the flange 14 and nut 15thereof and are held against endwise movement by an interposed sleeve 16. The outerrings 9 and 10 are similarly fitted in the counterbored portions of the hub, those of the inner set of bushings 4 being held between an'annular shoulder 17 and a screwring 18 and those of the outer set 5 between a similar shoulder 19 and the terminal screwcap 20 of the hub.= Thus mounted the wheel may turn with or independent of the bushings in the eventof the rollers becoming locked or .otherwise obstructed. Normally, however, orwhile there is entire freedom of movement throughout the rollersystem the friction andresistance opposing rotation of the bushings will be SllfllGlQIlt to effectually check movement thereof.

The racks 12, (shown in detail in Figs. 2, 3,

4,) in which the rollers are carried, are each formed of twin rings 21, which are secured together by pins, screws, or rivets 22. At equispaced pomts throughout the adjoining faces of the rings 21 a series of oppositely-disposed tapering sockets 23'are formed, which when the rings are united combine to form pockets or retaining-recesses in which the double. cone rolls. 11 are loosely held. The diameter of the sockets exceedsthe thickness of the ring-sections of the rack in which they are formed, as shown in Fig.4, and such sections are in consequence cut through at opposite sitles to the depth of the sockets, thus forming a series of spaced slots 24 throughout the inner and the outer periphery of the rack through which the rollers project, as shown in Fig. 3. The rack in cross-section conforms approxi- 3 7 recesses having inner and outer openings narmately to the shape of the rollers andlin the assembled bearing is supported by the same clear of the bushings, as shown in Fig. 1.

From the foregoing it will b'e' seen'that all sliding motion between the relatively moving parts is done' away with and that a rolling contact only is possible under normal conditions. The greatest' possible ease 1s thus obefiort. v p I Having thus described my invention, I

claim-+- 1. A roller-bearing comprising a seriesof double-cone rollers, a rack having sockets tatained in. turning with a minimum starting poring in opposite directionsfin which-the rollers are separately contained, and sectional the rollers are spaced, and bushingsproviding bearings for the rollers at opposite ends thereof.

3. A roller-bearing comprising a series of free, double-cone rollers, a rack conforming in cross-section to-the shape ofthe rollers in which the roller'sare separately contained in rower than the diameter of said rollers, and a sectional bushing providing bearings for the rollers at the ends thereof only.

4. A roller-bearing comprising aiserles of form separate double-conical containing pockets aving inner and outer openingsof less width than the diameter of the rollers,

and a sectional bushing adapted to serve as a race therefor."

I 5. A roller-bearing com rising a series of doublecone rollers, a racfi formed of twin sectionshaving each a series of conical recesses;-whicl1 combine to provide separate double conicalcontaining-pockets for'the I rollers, and a. sectional bushing adapted to serveas arace therefor.

6. A roller-bearing comprlslnga series of double-pone rollers, atwo-part rack compris- 35 double-cone rollers, a sectional'rack for the i rollers, the members of which-combine. to

ingcountcrpart sections, each part having tapering recesses which combine to provide bushing adapted to serve as a race therefor.
